Specification of Letters Patent. Patented De@ 25,v 1917.

Application filed Getober 217,319.16. Serial. No. 126,937.

To all 'whom t may concern.'

Be it known that I, JOHN. I. STEEN, a citizen of the United States, residing at lVaukega-.in in the county ot' Lake and State y of lllinois, have invented certain new and useful Improvements in Locks, of which the following is a specification.

This invention relates to improvements in locks of the keyless type and one object is to produce a lock of this class adapted particularly for use on trunks. A further vobject is to produce a lock of this type that is A dotted lines showing the lock in open position.

Fig. 3 is a vertical sectional View through the lock.

Fig. 4 is a front View of the lock casing mechanism with the tongue and connections raised.

Fig. 5 is a front View of the base plate.

' Fig. 6 is a plan view of the indicator.

Fig. 7 is a top plan view of the rotary' tumbler.

Fig. S is a side elevation of Fig. 7.

Fig. 9 is a plan view of another rotary tumbler.

Fig. 10 is a side elevation of Fig. 9.

Like reference characters denote corresponding parts throughout the several views.

IThe reference numeral 1 denotes a leaf designed to be secured to the top of a trunk and the numeral 2 denotes a base plate to be secured to the body of the trunk. The base plate is formed with an annular bulged portion or casing 3 adapted to receive an annular cap 4, the closed end or base 5 of said cap being designed, when the lock is locked, to abut the casing 3. The base of said cap is apertured to receive the pins 6,two in number, which are carried by the casing 3, said pins each being formed with two grooves 7 to permit lrotation of the tumblers. The cap 4 is formed, further, with an annular shoulder 8 which is formed with two recesses 9 with which the said pins .6 may register. Loose within the cap 3V is a rotary tumbler 10 formed with two marginalrecesses 11 to permit its withdrawal over thesaidpins 6 and vwith an annular shoulder 12 spaced vaway from its outer edge. .-A. lug 13 y1s vformed upon said tumbler beside the shoulder 12. i

A second tumbler 14`comprising a base. ringl o'rmed with marginal -recessesl, twoin number to permit its withdrawal over the said pins 6, isprovided. Beneath the ring 15 is an annular shoulder' 17 adapted to rest directly upon the annular shoulder 12 of the tumbler 10 and a lug 18 depending .below said ring 15 is` adaptedfor-engagement with the lug 13 of said tumbler 10. The tumbler 14, further,4 comprises the stepped annular portions 19, 20 and the threaded stem 21, which .risesfrom the annular portion 20, and is-formed with the annular groove 22 adapted to register witha ,slot 23 in lthe' interiorly threaded knob 24 when-the knobi is in position upon said? stem. The slot 23 is adaptedto receivev a small pin (not shown) which will engage with the `grooved portions. of the stem' to prevent thel accidental removal of the knob.

The stem 21 carries .the indicator. 25 'which' rests upon the lannular portion 20 and is held in position bythe 1said knob andfis adapted for registration with any of the numbers arranged in a circle upon the face of a tongue 26 which is hinged at 27 to the leaf 1 and which is apertured to permit its passage over the stem 21 to the annular portion 19 to allow it to rest upon the portion 20 against which it is retained by the said knob 24; said tongue thereby carrying the cap, indicator and tumbler 14.

In Figs. 1 and 2 and in Fig. 3, full lines,- the lock is shown locked. To unlock the same the operator turns the knob 24 which turns the tumbler 14 which, through the medium of lugs 13 and 18, turns the tumbler 10 and also the indicator 25 which. through the medium of the numbers upon the tongue 26, will indicate the position of the rotary tumblers and when the same are in such position as to permit their removal from engagement with the pins 6, or in other words when said tumblers are in such position as to afford a clearance for the pins 6 the tuinblers, cap 4 and tongue 26 may be moved He now places the tongue` and tumbler 14,

carrying the indicator, upon the tumbler 10 and takesy a reading of the indicator upon said vtongue and the number With which the indicator registers will be one of the numbers of `the lock combination. He

now rotates the knob L4 until the lug lThe :recesses 16 in tumbler 14 are'nowv in alinement-vvit'h the recesses 11 ofl tumbler 10 and the operator now takes a second reading by means of the indicator `upon the -tongue 26' and :this number Will be the second number of the lock combination. 'By vvithdiaufingl his pencil from the" opening Vin the base 5 he may'noiv turn'theki'iob 24 and the llock-is locked. To unlock rit', vit `is but necessary -to turn. the indicator 'firstto theV rst lnumber of lthe combination .and lthen turn it back Vto the second number of the combination when the recesses in both tumblers will be found to register with vthe pins 6 and the lock is unlocked and may-be readily opened. A r-ib IB formed on the base plate serves as a buffer for 4the tongue 26;

casing and to be held thereby, said cap,

having an annular shoulder having pe- `riphera'lrecesses with which said pins are adapted to register, a rotary tumbler loose Within said cap vandhaving marginal recessesl for its clearance of said pins, and having-an'annular"shoulder spaced away f'fromits outer edge, said loosetumbler having alug 'adjacent said shoulder, a second tumbler positioned in said-cap and comprising a ring formed-with marginal recesses for itsclearance of said pins, said second tumbler' also `having 'an annular shoulder spaced from said fring and adapted'to rest fdire'ct'ly -up'on the annularshoulder of the 18 of tumbler 1% engages With lielug 13. i

- bler having a dug-adjacent said ring and V`adapted for engagement with the'lug-of said loose tumbler, saidsecondftumbler having,l in additi'onto a ste-ppedperipheral contour, `also a threaded stem Vreceived within an internally threaded `knob,:.1neans for the .re wtention ofthe flatter againstfturning, and l an` `indicator positioned upon 'said -stemf' Afor first referred lto tumbler, said second tuin registering 'with A graduations upon #said tongue. l A
